Description: Forward Secrecy is used to improve the security of communications transmitted across the Internet using public key cryptography.

The security of communications transmitted across the Internet can be improved by using public key cryptography. However if the public and private keys used in those communications are compromised it can reveal the data exchanged in that session as well as the data exchanged in previous sessions.
The concept of Perfect Forward Secrecy (PFS) is the property that ensures that a session key derived from a set of long-term public and private keys will not be compromised if one of the (long-term) private keys is compromised in the future. Online systems such as IPSEC can negotiate new keys for every communication and if a key is compromised only the specific session it protected will be revealed.
Forward Secrecy has been used as a synonym for Perfect Forward Secrecy but there is a subtle difference between the two. Perfect Forward Secrecy has the additional property that an agreed key will not be compromised even if agreed keys derived from the same long-term keying material in a subsequent run are compromised.
